Aly Raisman practically defines overachiever: At just 19, she's served as the captain of the U.S. Women's Olympic Gymnastics Team, won two Gold and one Bronze medals at the 2012 Summer Olympics, designed her own leotard line, and competed on Dancing With The Stars. Whew! Aly's words to live by? "You can't always be the best. You have to remember that everyone makes mistakes sometimes."

Even with all her incredible achievements, it's impossible to be the best at everything, even for an Olympic athlete like Aly. Once you accept that it's totally normal not to be perfect, you'll be surprised by your own fearlessness—and become even more confident with your newfound "I can do that!" attitude.
